Abstract: A method in a computer system for conducting a reward structure and implementing commissions in an online auction comprising the steps of: online consumers providing one or more items for bid on the online auction; the online auction announcing a drawing with a reward for the completed sales of any one of the items; online consumers completing sales for the items on the auction; the service provider receiving notification of the completed sales; sending a request to either one of the online consumers for a voluntary commission; receiving the voluntary commission from either one of the online consumers; issuing unique tickets to the successful bidders and successful sellers for their completed sales; entering the tickets into the drawing; selecting a winning ticket through a computer generated process at the time of the promotional event; and giving the reward to the winning ticket holder.
